]]> In the fall of 1915, the foundations of physics began to crack. Einstein’s new theory of gravity seemed to imply that it should be possible to create and destroy energy, a result that threatened to upend two centuries of thinking in physics. Einstein’s theory, called general relativity, radically transformed the meaning of space and time. Rather than being fixed backdrops to the events of the…

]]> Will 2024 be remembered as a banner year in the quest to understand the universe, or just an average one? That depends on whether a result from this spring turns out to be real. In April, physicists detected a hint of a signal suggesting that dark energy, the mysterious energy of space itself, may be weakening. “Hint” is the preferred term because the sign in the heavens isn’t quite robust…

]]> Most of today’s leading theoretical physicists have a shared perspective about what the next revolution in physics will look like. They think reconciling Albert Einstein’s general theory of relativity with quantum mechanics will require transcending the notion of space-time. Einstein’s theory attributes the force of gravity to curves in the space-time fabric, but beneath this fabric they hope to…

]]> For over a decade, Quanta Magazine has challenged and delighted fans with stories about the most fundamental questions in science. Today, in its most ambitious project to date, the magazine brings its audience into what might be the deepest mystery of all: the nature of reality itself. Many physicists now believe that space and time are not fundamental features of the universe…
